NOTES ON COLLECTING. 345 
on August 1st, I am glad to report that the whole of the larve success- 
fully pupated. The weather keeping very open, I somewhat deferred 
removing the pup from their habitations for the purpose of forcing 
them. An imago, a male, emerging crippled on the evening of 
October 18th, I removed the remaining pupe on the following day. 
Pending the getting of my forcing apparatus ready, I placed the pup 
on earth in two wooden boxes, having gauze coverings at the top, and 
removed them to the kitchen, the weather having turned very cold. 
The pupz, beyond being very lively, showed no signs of an early 
emergence of the perfect insects, and I was rather surprised, upon 
taking a final peep of them at midnight, to find, in one of the boxes, 
two imagines, a male and a female, on their backs on the earth, kicking 
violently. How long they bad been in this position I cannot say, but 
possibly for some little time. They had apparently emerged and failed 
to do what imagines of other species had found no difficulty in doing, 
that is to climb up the rough wooden sides of the box to the gauze 
covering at the top. This may have been due to the hooks at the end 
of their lees with which the species 1s provided not being suitable for the 
purpose. The two imagines which had emerged, immediately clung 
to my finger as it was offered to them in turn, squeaking while doing 
so. They fancied my rough coat for holding to, but, after some 
little trouble, and several minutes’ delay, I sueceeded in getting them 
to secure a good hold on the gauze. I observed that until they had 
managed to get a firm hold, their wings did not commence to grow. 
When I left them at two in the morning neither of the insects had 
entirely completed their growth nor folded their wings. The remain- 
ing two pupe I placed in my forcing apparatus, and obtained perfect 
insects from them. ‘The first, a female, emerged on October 24th, 
during my absence from home, and apparently between 7 and 9 p.m., 
as at eleven o’clock I found it with its wings folded. The remaining 
one, also a female, emerged on the following day at 10.15 p.m., I was 
at home at the time, and observed that, as it came up from the moss 
in the pot, and climbed up the twigs to the gauze to secure a hold, it 
squeaked almost as loudly as a mouse does. It was quite two hours 
after emergence before the insect had finished growing its wings and 
drying them, and it was not until 12.15 a.m. on the following morning 
that it had folded its wings. Two of the pups measured 21’ in 
length, and the remaining three 22"".. I had rather bad luck with the 
male imago which emerged on October 19th. I placed it in the 
killing bottle at 8°30 a.m. on the following (Saturday) morning, and on 
my return from town at 3 p.m. I found it still aliv e, the killine-bottle 
having almost entirely failed to act. The insect, mozeover, had exuded a 
whitish fluid, by rolling in which it had completely spoiled its Wings. 
After removing it from the killing-bottle it almost entirely recovered 
from the effects of the cyanide. This left me with three perfect 
specimens, all females, two of which measure 5’’ across the wings, and 
the third 52’. Although I have referred to the squeaking of the 
insect I am by no means satisfied that this is a correct term to use. 
The noise emitted appears to me to be produced by a movement of the 
joints, or some of the joints, of the legs. The curious thing about it 
to my mind is that apparently the insect can emit the sound or not as 
it pleases, and it generally does so if alarmed.—A. Russexx, F.E.S.,
